Bombyx mori (L.) (Lepidoptera: Bombycidae) is an important economic insect, and Exorista sorbillans (W.) (Diptera: Tachinidae) endoparasitic pest of larval B. mori. Dimethoate less toxic to than E. used in sericulture controlling sorbillans. To investigate the effects dimethoate treatment on gut microorganisms physiological functions mori, 16S rRNA sequencing was analyzed composition structure microbiota. This study investigated their role enhancing silkworm resistance by screening dominant populations after treatment. The results indicated that did not alter bacterial groups silkworm; however, it significantly increased abundance bacteria Methylobacterium Aureimonas, decreased Enterobacterales, Bifidobacterium, Blautia, Collinsella, Faecalibacterium, Prevotella. Eleven strains dimethoate-resistant were selected through vitro culture, all which unable grow when as a carbon source. Additionally, germ-free model established assess detoxifying enzyme activity midgut. revealed symbiotic microbiota can enhance increasing detoxification activity. identifies novel pathway for based microbiota, providing new insights into insecticide metabolism.

Abstract Spodoptera frugiperda (fall armyworm) poses a substantial risk to crops worldwide, resulting in considerable economic damage. The gut microbiota of insects plays crucial roles digestion, nutrition, immunity, growth and, sometimes, the degradation insecticides. current study examines effect synthetic insecticides on microbiome third instar S. larvae using both culture‐dependent techniques and 16S rRNA gene sequencing for bacterial community profiling diversity analysis. In untreated larvae, approach revealed diverse dominated by phyla Firmicutes, Proteobacteria Bacteroidota, with key genera including Bacteroides , Faecalibacterium Pelomonas . parallel, 323 strains were isolated assigned orders Bacillales, Burkholderiales, Enterobacterales, Flavobacteriales, Lactobacillales, Micrococcales, Neisseriaies, Pseudomonadales, Sphingobacteriales Xanthomonadales. prevailing culturable species included Serratia marcescens Klebsiella variicola Enterobacter quasiroggenkampii Treatment sublethal concentrations three (broflanilide, spinosad indoxacarb) caused significant changes composition. Treated showed shift towards increased abundance decreased Firmicutes. Specifically, Acinetobacter Rhodococcus dominant treated samples. Functional predictions highlighted metabolic versatility involving nutrient processing, immune response, detoxification, xenobiotic metabolism, stress suggesting microbial adaptation insecticide exposure. Network correlation analysis disrupted interactions altered structures under treatment. These findings enhance our understanding how impact may inform future strategies managing pest resistance through microbiome‐based approaches.
